What's the best way to weld them up?

Mig with stainless wire? How thick?

Stick welder with a small diameter rod?

Take them to a pro and write a check?

Thanks for the help.

You could TIG weld them Same as welding mild steel or 4130. For best weld you should fill the header tubes with argon so the weld doesn't get contaminated from the back side. There are other ways to weld stainless, but that's how I would do it.
